We are running Win 7 SP1 RSAT with a Server 2003 DC. We mainly use it to reset AD passwords. The performance is extremely slow (one minute of non-responsiveness per password reset). How do we improve the performance?

you should make sure that you do not have any configuration problems (especially in regards to DNS) with your domain. Also, for better troubleshooting, you should run Wireshark on the W7 workstation capturing the network traffic while attempting the password reset and see where the holdup happens. –  the-wabbit Jan 9 '12 at 16:15

There aren't really enough details here to give a definitive answer, so I'll share this nugget of knowledge:

If you have an AD problem, it's probably because of a DNS issue. If you checked DNS and you still have a problem, it's because you missed the DNS issue that's causing your problem.

This thread has a bit more information relating to this problem.

I am having the issue and have googled it quite a bit. No true solution seems to have been found, that I can uncover, but some have reported improved performance by disabling WINS on all network adapters. This has not improved performance in my case, but perhaps it will help you. In any case, it is another piece of the puzzle. If I find any other resolution or partial resolution, I will report back.

Try this:

To disable NetBios, go to Control Panel > Network and Internet > Network Connections > select a network adapter > Properties [context menu item] > 'Internet Protocol Version 4 (TCP/IPv4)' [list item] > Properties [button] > Advanced... [button] > WINS [tab] > uncheck 'Enable LMHOSTS lookup' and select 'Disable NetBIOS over TCP/IP' [radio item] > OK > OK
